6 Claims.

This invention relates to conveyor apparatus for handling articles andis especially useful in the handling of vulcanizable rubber-likearticles in strip form although the invention is also useful in handlingotherarticles of other materials, especially those in long strip form.

In the manufacture of strip articles of rubber material without manualhandling and to provide improved apparatus for the purpose.

Other objects are to provide for deposit of a plurality of stripssimultaneously, and to provide for guiding of the strips to properposition on the pans.

These and other objects will appear from the following description andthe accompanying drawings.

Of the drawings,

Figs. la and 1?) show in continuation of each other a side elevation ofapparatus constructed in accordance with and embodying the invention,parts being broken away.

Fig. 2 is a section taken on line 2--2 of Fig. 1.

Fig. 3 is a plan view thereof, parts being broken away.

4 is a wiring and piping diagram.

Referring to the drawings, the numeral Hl designates a supporting framehaving bearings H, !2 in which a pair of shafts l3, M are rotatablymounted in parallel relation to each other.

A pair of sprockets i5, of equal diameter, are mounted on shaft i3 forrotation therewith and for sliding movement axially thereof, eachsprocket having a key for slideably engaging a long keyway in the shaft.The hubs of the sprockets are formed with shifter grooves i8, it. Adouble-acting pressure fluid. operated cylinder '20 is mounted on theframe it and its piston rod. 21 has a shifter fork 22 engaging in grooveif; of the sprocket i5. A similar cylinder 23 mounted on frame it has apiston rod 2d with a shifter fork 25 engaging in groove ii of sprocketH5. The arrangement is such that the sprockets IE, it may be moved bythe cylinders from the full line positions of Fig. 2 to the dot-and-dashline positions thereof.

Shaft it is similarly provided with sprockets 2 3% 3i slideably mountedthereon and doubleacting cylinders 3'2, 33 are provided for shifting thesprockets in similar manner.

Shaft is is driven from any convenient source of power (not shown) by achain 34 engaging a sprocket 35 fixed to the shaft. Sprockets l5 and 36are connected by an endless flexible conveyor member such as a chain 36and sprockets l5 and 3! are connected by an endless flexible conveyormember, such as a chain 3! parallel and opposed thereto. Chains 36 and'37 have lateral extensions such as rods 40, 4| extending therefrom, therods or extensions extending toward the opposite chain and beingarranged in spaced-apart noncontacting intercalated relation so ascollectively to provide a support for the strip material or otherarticles, which support thus bridges the space between the chainscompletely and makes it possible to support a plurality of individualarticles, such as flexible strips,

simultaneously.

The strips 42 of material are delivered to the rods to, it by a conveyorbelt 43 trained about pulleys M, 45. Pulley 44 is fixed to a shaft 46--journa1ed in bearings 41 on frame it) above chains 36, 3? so as todeliver the strip therefrom. Pulley do is secured to a shaft 48 which isjournaled in bearings 29 on a frame 51. A chain 58 drives shaft &8 froma convenient source of power (not shown) through a sprocket 59 on theshaft.

For directing the strips 42 to a position over the pan 5! guide fences 5I, 52 are adjustably mounted on the frame it in position to overhang theconveyor chains 35, 31, and have rounded ends 53, 54 for deflecting thestrips. Such fences also act as stripper means for holding the articlesas the rods are withdrawn.

For operating the cylinders 20, 2t, 32, 33, 9. limit switch 55 islocated on the fence 52 in the path of the strips and is closed bycontact with the leading ends of the strips. A solenoid fourway valve 55operates when energized by closing of the switch to control flow ofpressure fluid to the cylinders 2t), '23., 52, 33 to separate the chains35, at and drop the strips in the pan 5!] supported by the frame in, andwhen the solenoid is deenergized. reverses flow to the cylindersreturning the chains to the full line positions.

The operation of the apparatus is as follows: Strips t2 are fed by thebelt conveyor 43 onto the rods it, M which are travelling at the same orslightly increased speed. The fences 5|, 52 guide the strips to aposition over the pan 50. When the leading ends of the strips contactthe 55 limit switch, the chains 36, 3? move laterally withdrawing therods 46, 4| from beneath the strips which drop onto the pan. The panwith the strips 42 thereon is removed and replaced by an empty panduring the advance of the next group of strips.

The strips may be rapidly loaded onto pans in the desired order withoutmanual handling.

Variations may be made without departing from the scope of the inventionas it is defined by the following claims.
